Siderite

The most common iron carbonate is siderite (FeCO3 ), a frequent constituent of carbonate sediments and rocks on Earth. Siderite has a low-temperature transition at 30–35 K ( Housen et al., 1996 ), distinctively different from that of pyrrhotite ( Section 5.08.3.9 ). Siderite is paramagnetic at ordinary temperatures and carries no NRM.
